Really. Seagate enterprise highest duty cycle "nearline" drives, 5 year warranty (which I not long ago had to use for one of the 2 I bought back then). A SAS interface adds $20 currently; models and Newegg prices: Constellation ES ST32000444SS 2TB $265 7/15/11 SAS Constellation ES.3 ST4000NM0023 4TB $230 10/21/15 SAS Constellation ES.3 ST4000NM0033 4TB $210 10/21/15 SATA ADDED: Samsung magnetic hard drives are going to be bad for historic price comparisons, for Seagate bought their unit in 2011 (http://www.seagate.com/about-seagate/news/seagate-completes-aquisition-samsungs-hdd-business-pr/ http://www.seagate.com/about-seagate/news/seagate-completes-...). Per that press release, "To ease the transition of products and technologies, Seagate will retain certain Samsung HDD products under the Samsung brand name for 12 months"; Your old price might be lower than normal due to that sale, and/or whatever prompted Samsung to get out of the business; the current price is close out inventory of older generation technology.
